The stop layer is disposed on the second surface of the carrier. The barrier layer is disposed on the stop layer and protruded from the first surface of the carrier. The encapsulant is disposed on the first surface of the carrier. Further, the encapsulant has a side surface disposed on the barrier layer.

BACKGROUND 1. Technical Field

The instant disclosure relates to, amongst other things, a semiconductor device package, and a semiconductor device package having an area or space devoid of an encapsulating material.

2. Description of Related Art

A molding process is a packaging technology for a semiconductor package, which is used to protect a substrate and components on the substrate. However, in some implementations not all regions of the substrate should be covered by the encapsulating material (also referred to as a molding compound), such as in antenna-on-package (AoP) implementations, in which it may be desirable to perform impedance matching of a path from a component to an antenna. Thus, a semiconductor device package can have a non-molding area or space (an area or space devoid of the encapsulating material), and a user can readily adjust the impedance matching by adjusting surface mount technology (SMT) passive components after the molding process.

The region exposed from the encapsulating material 131 is the non-molding area 15. In the non-molding area 15, there is substantially no encapsulating material 131 disposed on the upper surface 11 of the carrier 10, and the die 151 and the component 153 disposed on the upper surface 11 of the carrier 10 are not covered by the encapsulating material 131 and thus are exposed. Further, a conductive layer 14 is disposed on the upper surface 11 of the carrier 10. The conductive layer 14 may comprise a stop layer or comprise a stop layer and a barrier layer. The conductive layer 14 may be substantially located at or/and extend along the interface between the molding area 13 and the non-molding area 15.

Referring to FIG. 2, two ends of the conductive layer 24 are respectively located at two adjacent sides 201, 202 of the carrier 20. Thus, the non-molding area 25 is substantially located at the corner of the upper surface 11 of the carrier 10.

FIG. 3 shows a semiconductor device package 3 in accordance with an embodiment of the instant disclosure. In particular, the semiconductor device package 3 may have a molding area 33 and a non-molding area 35.

FIG. 4A, FIG. 4B, FIG. 4C, FIG. 4D, FIG. 4E and FIG. 4F show a method of manufacturing a semiconductor device package 4 (as shown in FIG. 4F) in accordance with an embodiment of the instant disclosure. As shown in FIG. 4A, a carrier 41 has an upper surface 411 and two recesses 410 formed in the upper surface 411. The carrier 41 may have recessed surfaces 412 (e.g. that defines a bottom of the recess 410) recessed with respect to the upper surface 411. Stop layers 42 may be respectively received within the recesses 410 and thus respectively disposed on the recessed surfaces 412. In other words, the stop layer 42 may be embedded in the carrier 41. A barrier layer 43 may be disposed on the stop layer 42 and protruded from the upper surface 411 of the carrier 41. The barrier layer 43 and the stop layer 42 may be integrated with each other. Moreover, the stop layer 42 and the barrier layer 43 may be made of the same material. Referring to FIG. 4A, the cross-sectional width of the stop layer 42 is greater than the cross-sectional width of the barrier layer 43. Especially, the combination of the stop layer 42 and the barrier layer 43 may be substantially inverted T-shaped. At least two electronic components 481, 482 are disposed on the upper surface 411 of the carrier 41.

As shown in FIG. 4A, the barrier layer 43 may have a side surface 431 connecting to the upper surface 421 of the stop layer 42. Further, there may be a space between the side surface 431 of the barrier layer 43 and the carrier 41. In addition, the barrier layer 43 may further have a side surface 432 opposite to the side surface 431. At least a portion of the side surface 432 may be substantially attached to the carrier 41. Moreover, a portion of the upper surface 411 of the carrier 41, which is located between the recesses 410, may further comprise a wetting layer 49.

Further, with reference to FIG. 4B, a glue is dispensed on the portion of the upper surface 411 of the carrier 41 between recesses 410. Since the barrier layers 43 are protruded from the upper surface 411 of the carrier 41, the glue will not flow across the barriers 43. That is, the removable/sacrificial layer 47 will be formed between the barriers 43. Further, the glue may flow into the space between the side surface 431 of the barrier layer 43 and the carrier 41. In addition, since the portion of the upper surface 411 of the carrier 41 between the recesses 410 may further comprise the wetting layer 49, the glue will be smoothly distributed and the removable/sacrificial layer 47 will be evenly formed between the barriers 43.

With reference to FIG. 4C, an encapsulating material 40 is disposed on the carrier 41 and encapsulates the upper surface 411 of the carrier 41, the stop layers 42, the barrier layers 43, the removable/sacrificial layer 47 and the components 481, 482. That is, the encapsulating material 40 covers the upper surface 411 of the carrier 41, the stop layers 42, the barrier layers 43, the removable/sacrificial layer 47 and the components 481 and 482.

With reference to FIG. 4D, portions of the encapsulating material 40 are removed by a laser process and thus portions of the barrier layers 43 are exposed. Thereby, the encapsulating material 40 is divided into three portions 44 and 45, wherein the portions of the encapsulating material 44 are attached to the upper surface 411 of the carrier 41 and the barrier layers 43 and the portion of the encapsulating material 45 is attached to the removable/sacrificial layer 47. In particular, while removing the portions of the encapsulating material 40 by the laser process, the laser will be projected on the barrier layers 43 or on the barrier layers 43 and the stop layers 42 and thus will not damage the carrier 41.

With reference to FIG. 4E, the removable/sacrificial layer 47 is removed by physical methods or chemical methods, such as a water washing process. Further, the portion of the encapsulating material 45 attached to the removable/sacrificial layer 47 is removed (e.g. while removing the removable/sacrificial layer 47). After removing the removable/sacrificial layer 47 and the portion of the encapsulating material 45, the portions of the encapsulating material 44 remain on the carrier 41 and the portion of the upper surface 41 between the recesses 410 and the wetting layer 49 are exposed. Moreover, a portion of the barrier layer 43 which is protruded from the upper surface 411 of the carrier 41, such as the portion of the side surface 431 above the upper surface 411 of the carrier 41, will be exposed as well. Further, the portions of the encapsulating material 44 are disposed on the upper surface 411 of the carrier 41.

As shown in FIG. 4E, the portion of the encapsulating material 44 may have a side surface 441 standing on the barrier layer 43. In addition, the glue may flow into the space between the side surface 431 of the barrier layer 43 and the carrier 41. Thus, after removing removable/sacrificial layer 47, the entirety of the side surface 431 of the barrier 41 may be exposed.

With reference to FIG. 4F, at least one electronic component 483 is disposed on the portion of the upper surface 41 between the recesses 410. Further, a shielding layer 445 may be formed on the portion of the encapsulating material 44 and connected to the stop layer 42 and the barrier layer 43. The shielding layer 445 may be grounded by the stop layer 42 and barrier layer 43.

As shown in FIG. 5A, a carrier 51 has an upper surface 511 and two recesses 510 formed in the upper surface 511. The carrier 51 may have recessed surfaces 512 (e.g. that defines a bottom of the recess 510) recessed with respect to the upper surface 511. Stop layers 52 may be respectively received within the recesses 510 and thus respectively disposed on the recessed surfaces 512. In other words, the stop layer 52 may be embedded in the carrier 51. A barrier layer 53 may be disposed on the stop layer 52 and protruded from the upper surface 511 of the carrier 51. The barrier layer 53 and the stop layer 52 may be integrated with each other.

Moreover, a portion of the upper surface 511 of the carrier 51, which is located between the recesses 510, may further comprise a wetting layer 59.

Further, with reference to FIG. 5B, a glue is dispensed on the portion of the upper surface 511 of the carrier 51 between recesses 510. Since the barrier layers 53 are protruded from the upper surface 511 of the carrier 51, the glue will not flow across the barriers 53. That is, the removable/sacrificial layer 57 will be formed between the barriers 53. Further, the glue may flow into the space between the side surface 531 of the barrier layer 53 and the carrier 51. In addition, since the portion of the upper surface 511 of the carrier 51 between the recesses 510 may further comprise the wetting layer 59, the glue will be smoothly distributed and the removable/sacrificial layer 57 will be evenly formed between the barriers 53.

With reference to FIG. 5C, an encapsulating material 50 is disposed on the carrier 51 and encapsulates the upper surface 511 of the carrier 51, the stop layers 52, the barrier layers 53, the removable/sacrificial layer 57 and the components 581, 582.

With reference to FIG. 5D, portions of the encapsulating material 50 are removed by a laser process and thus portions of the barrier layers 53 are exposed. Thereby, the encapsulating material 50 is divided into three portions 54 and 55, wherein the portions of the encapsulating material 54 are attached to the upper surface 511 of the carrier 51 and the barrier layers 53 and the portion of the encapsulating material 55 is attached to the removable/sacrificial layer 57. In particular, while removing the portions of the encapsulating material 50 by the laser process, the laser will be projected on the barrier layers 53 or on the barrier layers 53 and the stop layers 52 and will not damage the carrier 51.

With reference to FIG. 5E, the removable/sacrificial layer 57 is removed by physical methods or chemical methods, such as a water washing process. Further, the portion of the encapsulating material 55 attached to the removable/sacrificial layer 57 is removed (e.g. while removing the removable/sacrificial layer 57). After removing the removable/sacrificial layer 57 and the portion of the encapsulating material 55, the portions of the encapsulating material 54 remain on the carrier 41 and the portion of the upper surface 51 between the recesses 510 and the wetting layer 59 are exposed. Moreover, a portion of the barrier layer 53 which is protruded from the upper surface 511 of the carrier 51, such as the portion of the side surface 531 above the upper surface 511 of the carrier 51, will be exposed as well. Further, the portions of the encapsulating material 54 are disposed on the upper surface 511 of the carrier 51.

As shown in FIG. 6A, a carrier 61 has an upper surface 611 and two recesses 610 formed in the upper surface 611. The carrier 61 may have recessed surfaces 612 (e.g. that defines a bottom of the recess 610) recessed with respect to the upper surface 611. Stop layers 62 may be respectively received within the recesses 610 and thus respectively disposed on the recessed surfaces 612. In other words, the stop layer 62 may be embedded in the carrier 61. A barrier layer 63 may be disposed on the stop layer 62 and protruded from the upper surface 611 of the carrier 61.

Further, with reference to FIG. 6B, a glue is dispensed on the portion of the upper surface 611 of the carrier 61 between recesses 610. Since the barrier layers 63 are protruded from the upper surface 611 of the carrier 61, the glue will not flow across the barriers 63. That is, the removable/sacrificial layer 67 will be formed between the barriers 63. Further, the glue may flow into the space between the side surface 631 of the barrier layer 63 and the carrier 61. In addition, since the portion of the upper surface 611 of the carrier 61 between the recesses 610 may further comprise the wetting layer 69, the glue will be smoothly distributed and the removable/sacrificial layer 67 will be evenly formed between the barriers 63.

The barrier layer 73 has a top surface 733 which may be substantially coplanar with the upper surface 711 of the carrier 71. Moreover, the stop layer 72 and the barrier layer 73 may be made of the same material.

Further, with reference to FIG. 7B, a glue is dispensed on the portion of the upper surface 711 of the carrier 71 between recesses 710. The glue will flow into the space between the side surface 731 of the barrier layer 73 and the carrier 71, and thus the glue will not flow across the barriers 73. That is, the removable/sacrificial layer 77 will be formed between the barriers 73. In addition, since the portion of the upper surface 711 of the carrier 71 between the recesses 710 may further comprise the wetting layer 79, the glue will be smoothly distributed and the removable/sacrificial layer 77 will be evenly formed between the barriers 73.

With reference to FIG. 7C, an encapsulating material 70 is disposed on the carrier 71 and encapsulates the upper surface 711 of the carrier 71, the stop layers 72, the barrier layers 73, the removable/sacrificial layer 77 and the components 781, 782.

The carrier 91 may have recessed surfaces 912 (e.g. that defines a bottom of the recess 910) recessed with respect to the upper surface 911. Stop layers 92 may be respectively received within the recesses 910 and thus respectively disposed on the recessed surfaces 912. That is, the stop layer 92 is embedded in the carrier 91. The recess 910 has two opposite side surfaces 913. 914 connecting to the upper surface 911 of the carrier 91. The side surfaces 913, 914 of the recess 910 stand on the stop layer 92. That is, the top surface 923 of the stop layer 92 is recessed with respect to the upper surface 911 of the carrier 91. The stop layer 92 may have two opposite side surfaces 921 and 922. The distance between the side surface 921 of the stop layer 92 and the side surface 913 of the recess 910 may be identical to the side surface 922 of the stop layer 92 and the side surface 914 of the recess 910. At least two electronic components 981, 982 are disposed on the upper surface 911 of the carrier 91. In addition, a portion of the upper surface 811 of the carrier 91, which is located between the recesses 910, may further comprise a wetting layer 99.

Further, with reference to FIG. 9B, a glue is dispensed on the portion of the upper surface 911 of the carrier 91 between recesses 910. The glue will flow into the recesses 910 but will not flow across the recesses 910. That is, the removable/sacrificial layer 97 will be formed between the side surfaces 913 of the recesses 910. In addition, since the portion of the upper surface 911 of the carrier 91 between the recesses 910 may further comprise the wetting layer 99, the glue will be smoothly distributed and the removable/sacrificial layer 97 will be evenly formed between the recesses 910.

With reference to FIG. 9C, an encapsulating material 90 is disposed on the carrier 91 and encapsulates the upper surface 911 of the carrier 91, the stop layers 92 the removable/sacrificial layer 97 and the components 981, 982.

With reference to FIG. 9D, portions of the encapsulating material 90 are removed by a laser process and thus portions of the stop layers 92 are exposed. Especially, the laser may contact a portion of the carrier 91 while removing portions of the encapsulating material 90, and thus the side surface 913′ of the carrier 91 will be damaged. Thereby, the encapsulating material 90 is divided into three portions 94 and 95, wherein the portions of the encapsulating material 94 are attached to the upper surface 911 of the carrier 91 and the portion of the encapsulating material 95 is attached to the removable/sacrificial layer 97.

Further, since the side surface 913′ of the recess 910 is damaged by the laser, the roughness of the damaged side surface 913′ of the recess may be greater than the roughness of the side surface 914 of the recess 910.
